Special interest groups pros and cons

Pros
They use a democratic process
They check the power of majority
They have the ability to motivate legislators
They provide positive solutions

Cons
They would often seek for the minority of people
They only have one track in mind
They are only effective for themselves
They would commit serious crimes

Hope this helped and please paraphrase!!!

The Bonus Army was a group of 43,000 demonstrators – made up

of 17,000 U.S. World War I veterans, together with their families and affiliated groups

– who gathered in Washington, D.C. in mid-1932 to demand early cash redemption of their service bonus certificates.
